SAN FRANCISCO -- Facebook wants to further court small businesses and ad agencies with improved tools to reach online audiences.

The social-networking giant on Tuesday announced it has redesigned its ad-buying and -reporting tool. The new advertising options are intended to give buyers ad placement recommendations based on their objectives. Also, it gives improved analytics to measure those results. Facebook calls it objective-based buying and reporting of advertisements.

"We're making these updates so marketers can focus on what matters to them most: driving results for their business," the company said in a blog post.
